How does the author use foreshadowing in Driving Miss Daisy?

Hoke is sixty years old when the play begins. He is an unemployed, uneducated African American. He has worked as a driver and deliveryman previously. He is pleased when Boolie hires him, both for the job and because he likes to work for Jews. He is extremely patient with Daisy and tolerant of her barely disguised prejudices. Hoke's gentle patience with Miss Daisy,despite her prejudice, foreshadows her acceptance and friendship later.
